Hey everyone! Yes, as Tomeu says, we basically did the same thing only that
we put the power supply, connectors, resistor connected to 5V, etc. in a

I think that in order to make this solution useful it should use a decent
(branded) ATX supply. It doesn't need great specs, but at least you should
be able to rely on the rail current specified in the label (which is not
always the case in generic supplies).

As soon as we finish a small wiki we are writing regarding the solution,
we'll send a link to it and we can share experiences with the idea.

Another problem is getting XO compatible cables. We used cables from broken
XO chargers, but this cables mostly (like 8 out of 10) break at the tip, so
they generally need to be fixed to be reliable. And they don't end un
looking pretty :)
